Presentation-Applications

There are several presentation packages available for Linux aside from
commercial pointing software. You can do your presentations by using
HTML itself. You can also try LATEXslide feature or better try
latex2HTML, §9.9.
Additionally you can try Open Office Impress (see the office software
section §9.6.1). However, there is an extension of the
LATEXslide class which can give you outstanding results with effects
that will not distract your audience. This is the
prosper class.
